6 Claims.

This invention relates to a pocket implement: and has for one of its objects the provision of an arrangement whereby a tool of some sort such as a nail file may be housed within a mechanical pencil.

Another object of the invention is the novel manner of mounting this nail file for assembly with the mechanical pencil.

Another object is to arrange for a snug, frictional fit of a cap over the tool for conveniently housing the same when not in use.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and

particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is an elevational view showing the pencil with the cap over the tool;

Fig. 2 is a view similar to Fig. 1 but showing the cap removed, its position being represented by dotted lines;

Fig. 3 shows the tool mounting member alone, looking at the same in a direction at right angles to the showing in Fig. 2;

Fig. 4 is a perspective view of the tool alone;

Fig. 5 is a perspective view of the resilient gripping band;

Fig. 6 is a sectional view through'the mounting member with the band in place; and

Fig. 7 is an elevational view with the mounting member in section and showing the tool or implement and the eraser as mounted therein.

Mechanical pencils usually provide somev sort of a propelling mechanism for the lead and are equipped with some sort of an arrangement for the exposure of an eraser at the opposite end; and in order to further utilize the capacity of the barrel of the pencil for housing additional use-.

ful parts, I have arranged for the mounting of a tool, which in this particular instance is a nail file, in the end of the barrel opposite to that in which the lead propelling mechanism is mounted, and have provided a cap which may be placed over the nail file to house the same in a manner similar to the mounting of the cap on a fountain pen; and yet I have provided an arrangement which by a simple unthreading of the parts exposes an eraser for use when desired; and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by whichthese advantageous results may be accomplished:

With reference to the drawing, l0 designates a tubular barrel comprising a body portion of the device, which is tapered at its forward end I l and 1936, Serial N0. 74,294

equipped with a point end mechanical movement I2 for propelling leads. the same being mounted in this barrel for convenient operation of the lead iii, in a known manner. The opposite end of the barrel I0 is internally threaded s at I4 for the reception of a tool mounting member or sleeve l5 and which is shown in greater detail in Fig. 6.

This sleeve I5 is a screw machine product and is provided with a central bore l6 inwardly from one end which joins a larger central bore ll extending inwardly from the opposite end. The juncture between said bores l6 and I1 forms a tapered shoulder IS. A recess I9 is provided in the outer surface of the sleeve for the reception and confining of a resilient band 20, one edge of which rests against the flange 2| extending outwardly from a point intermediate the end of the sleeve. On the opposite side of this flange 2| from the band 20 the sleeve is threaded as at 22 to fit into the threads M in the barrel ill. A slot 23 is provided in the end of the sleeve, which slot communicateswith the bore l6 and is of a. width to snugly receive the tool 24 here shown as a nail file when the same is placed in position, as shown in Fig. 3.

This nail file has a reduced shank portion 25 providing a shoulder 26 between the shank 25 and the portion 24 of the file. The shank portion 25 is of a size to closely fit the bore IS with a shoulder in the slot 23, while its lower end is split as at 21 with its opposite portions v28 spread as shown in Fig. '7, to engage the shoulder l8 and securely lock the implement or nail file in position in the sleeve. A rubber plug 30 may be positioned in the bore ll of the sleeve to complete this unit comprising the tool and eraser. This unit as shown in Fig. '7, is mountedin the end of the barrel ill, as shown in Fig. 2, from which position it may be readily removed for use of the eraser or rubber plug 30, when desired.

To complete the device, a cap 3| of tubular structure is provided of a size to freely receive the tool or nail flle 24 within it, the open end of this cap 3| is of a size to snugly frictionally grip the band 20 which is in the recess H! in the sleeve so as to slightly compress the same, which is possible due to the split 32 in the band and cause the band to snugly grip-the sleeve and also snugly grip the cap 3|, the grip being sufficient for entirely supporting the device from the cap so that a clip 33 provided on this cap may be used for effectively mounting the entire structure on the-edge of the pocket of the user. 7

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a pocket implement, a sleeve having a central bore of two diameters forming a shoulder between, a tool having a reduced shank forming a shoulder to engage one end of the sleeve when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said different diameters to engage the shoulder between said bores and hold the tool firmly in said sleeve.

2. In a pocket implement, a sleeve having a central bore of two diameters forming a shoulder between and a diametrical slot in one end, a blade-like tool having a reduced shank forming a shoulder to fit in said slot in one end of the I sleeve when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said difierent diameters to engage the shoulder between said bores and hold the tool firmly in said sleeve.

3. In a pocket implement, a metal sleeve having a central bore of two diameters forming a shoulder between, a tool having a reduced shank forming a shoulder to engage one end of the sleeve when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said different diameters to engage the shoulder between said bores and hold the tool firmly in said sleeve.

4. In a pocket implement, a tubular barrel having threads on the inner surface thereof, a sleeve having a central bore of two diameters forming a shoulder between and a diametrical slot in one end, a blade-like tool having a reduced shank forming a shoulder to fit in said slot in one end of the sleeve when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said different diameters to engage the shoulder between said bores and hold the tool firmly in said sleeve, said sleeve being provided with threads on its outer surface to engage the threads on the inner surface of said barrel.

5. In a pocket implement, a tubular barrel having threads on the inner surface thereof, a sleeve having a central bore of two diameters forming a shoulder between, a tool having a reduced shank forming a shoulder ,to engage one end of the sleeve when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said different diameters to engage the shoulder between said bores and hold the tool firmly in said sleeve, said sleeve being provided with a recess and a resilient band encircling said sleeve and located in said recess to frictionally fit a cap to house the tool.

6. In a pocket implement, a tubular barrel having threads. on the inner surface thereof, a sleeve having a central bore of two diameters forming a shoulder between and a diametrical slot in one end, a blade-like tool having a reduced shank forming a. shoulder to fit in said slot when the shank is in said smaller bore, the end of the shank being spread into said larger bore at the junction of said different diameters to engage the shoulder between said bores, said sleeve being provided with threads on its outer surface adjacent the end having the larger bore to engage threads on the inner surface of said barrel and project the tool therefrom, and a resilient band encircling the sleeve at its other end to frictionally fit a cap to house the tool when desired.
